I PROCESS OEMANUFACTUBING VERY EXT NSIBLE' PAPER.

To a7? whom it may concern:

Be it known that l. Anamun'r Grnssnen. a subject of the German Emperor.residing at Niederau, near Diiren. Germany. have invented certain newand useful Improvements in the Process of Manufacturing Very ExtensiblePaper; and I do hereby declare the following to be a full. clear. andexact descriptioh of the invention. such as will enable others skilledin the aft to which it appertains to make and use the same.

Thesubject-matter of my invention. is an improved process ofmanufacturing very extensible paper, such as e. pa per or the like.

According to my invention the material is first worked upintoverythingwebs which are united either individually in succession, or ingroups and then in these groups in succession. on a long wire-clothpaper-making machine, whereby it is possible to manufacture'heavy paperof very greasy material, the fibers being well felted and a very highdegree of extensibility being obtained by working up the material inindividi-lal layers.

A particularly suitable form of apparatus for carrying'my improvedprocess into practice comprises several superposed sets of wire-cloth,in which the end guide rolls of r sack or cable the top machine arelocated in front of and behind the first press-roll of the loweranachineand in this manner admits of an optional number of webs of paper beingbrought together in long wire-cloth papermaking machines. p

The material employed for manufacturing sack and cable paper is verygreasy and therefore can only with difliculty be-treed,

from Water on the long wire-cloth paper .lnaking machinein the case ofheavy paper. Consequently the individual fibers of the paper are notfelted so readily asin thecase of so-called harshly ('l'bsch) groundmaterial; Now in order to enable thoroughly good telt1ng,; according tomy invention the material is Worked up on several sets ot wire-clothsinto individual, very thin webs, of paper within which the fibers canfelt much more readily on the sets of \virecloths,

and these individual Webs are subsequently united on the lowerpaper-making machine to form a thick web, and in this manner a speciallygreat degree of strength is given to the product. It is to be emphasizedas esscntial that when bringing together such Specification of LettersPatent. Patented Feb, 27, Application tiled March 26, 19th. Serial No.551,710.

websof paper a very greattdegree of extensibility is obtained both inthe transversedirection and in the longitudinal direction of the stripof paper, which is a principal requirement of the product, in orderthatthe In a modified, very advantageous mode of carrying my inventioninto practice an in-- sertion' ot textile material, wire or othersultable material 13 introduced between two or more webs: this insertioncomes from a stock 'reel, guided by a guide roll and so placed betweenthe Webs that; it runs in at t i a very acute angle to one of the sameand an injurious websfl One form of apparatus suitable ,for'carrying myprocess into practice is represented by way. of example in theaccompanying drawing, five long Wire-cloth paperm'aking pressure againstany of the machines being shown superposed. inthree.

Referring to the drawing, the paper Web coming with the Wire-cloth afrom the long wire-cloth paper-making machine A is brought, after ithaspassed the couchingroll I), bymeans of the end guide roll 0 onto the webof wire-cloth a? ofthe machine B,

this end guide'rollk' being located in 'front of the first press-roll dof the machine B. Simultaneously, the web of paper coming from themachine I over the wire-cloth'2 is supplied, after it has passed thecouching-roll I), with the aid of the end'guide roll 3 to the wire-clotha of themachine B, the end guide roll 3 being located in the directionof working immediately behind the this first press-roll d by the endguide roll 3 so that on the machine B a strip of paper consisting offive webs is brought under the couching roll b It is obvious that themanufacturer can 60' tilled sacks can yield during transit andconsequentlyinot tear.
